- the connector is a low voltage electrical connector in two parts.
- the connection is maintained by magnetic force and separated by pull force.
- the disconnection is easily achieved by hand (without tools).
- the connector In engaged state, the connector provides constant electrical connection in place, as well as through unlimited rotation of the male component 12 or the female component 14 in either clockwise or counterclockwise direction.
- FIG. 3 an assembly view is shown of the rotatable magnetic electrical connector 10 , having two main components: a male component 12 and a female component 14 .
- the female component is shown in more detail in FIGS. 1A-1C .
- the male component is shown in more detail in FIGS. 2A-2C .
- the male component 12 is sized and shaped to snugly fit inside an interior cavity 44 of the female component 14 .
- the male component 12 may be fully or partially tapered in shape, the female component 14 having an interior cavity 44 of the same tapered shape.
- the fit is intended to provide a close tolerance mating of the two components, which in turn provides sufficient friction to prevent slipping of one component relative to the other.
- various mating shapes of components may be used, it is preferred that the cross-sections of the male component and female component be generally circular.
- the components are capable of secure mating relation without the need for other locating means or alignment means.
- the tapered shape is considered preferable for several reasons.
- the tapered shape is considered beneficial for closer tolerance between the components (approaching zero tolerance).
- the components can be made to have a very secure, “locked together” mating, even apart from their magnetic bond.
- the components resist side-to-side or pivotal movement relative to the center axis of the female component (i.e. the components do not rattle or slide relative to each other).
- the tapered fit does permit the frictional bond to be broken relatively easily by hand.
- the male component and female component are adapted for magnetic interconnection.
- the male component 12 may be comprised of a magnet-sensitive metallic material, such as the housing 16 , which is attracted by one or more magnets 30 in the female component 14 .
- a magnet-sensitive metallic material such as the housing 16
- the magnets may be rare earth magnets, such as neodymium, or any suitable magnetic material.
- the magnets are ring-shaped and mounted proximate to the interior cavity of the female component.
- the male and female components are not necessarily entirely metal.
- the electrical leads and contacts be made of a material that is functional to conduct electricity, and that the magnetic and magnet-sensitive portions of the male and female components co-operate to form a magnetic bond to retain the components together.
- the electrical function of the connector is provided by wires (leads) 18 , 36 and electrical contacts 24 , 34 , which may be physically brought into connection when the male and female components are mated together magnetically.
- one or both of the electrical contacts 24 , 34 may be spring-biased, to facilitate secure connection.
- the male component may include a steel coil spring 22 to bias the contact 24 (such as Tellurium) into abutment with the corresponding contact 34 in the female component (such as Tellurium).
- a black (negative) lead is also provided 40 . Current is carried through the connector to a light bulb or appliance via lead 18 .
- the electrical wires and contacts are provided to be housed within a housing 16 (e.g. stainless steel).
- a housing 16 e.g. stainless steel
- one or more washers may be provided 20 .
- the component may be packed with a pressure-fit retainer, such as a Nylatron retainer 26 .
- the electrical wires and contacts are provided to be housed within a housing 28 (e.g. stainless steel).
- the magnet rings 30 preferably are mounted within the housing below the cavity 44 .
- the interior parts are preferably secured using one or more washers 32 .
- Suitable washers may be made of any insulating material, such as Delrin.
- the component may be packed with a pressure-fit retainer, such as a Nylatron retainer 38 to guard against relative movement and wear within the female component.
- the female component may also be provided with a nut 42 which engages a threaded exterior portion on the steel housing 28 .
- the female component is adapted to fit into new and existing millwork (platforms, showcases, cabinets, tables, etc.), as well as wall board and paneling.
- the male component could be used as an attachment to LED and halogen light fixtures as well as, any low voltage AC DC appliance that conforms to accepted electrical standards (such as CSA, UL or European standards).
- the connector It is an advantage of the connector that its versatility allows for installation in horizontal, vertical and overhead positions, as well as providing 360-degree rotation, such as for light fixtures.
- the magnetic connection, as well as the snug fit of the components provides the overall assembly with a high level of stability (against tipping, and lateral pull and “shearing” forces). This is achieved with a relatively small “footprint” of the female component.
- the female component in use as a fixture/base for a table lamp
- a footprint can be small as about 1.25′′ in diameter.
- a table lamp having a standard AC base can have a footprint between 4′′ and 10′′ in diameter or more.
- the connector can be installed into existing millwork, multiple female components can be installed in handy locations, to permit male-component equipped appliances and light bulbs to be swapped in and out as desired.
- the small footprint and smooth top surface (which can be recessed to lie flush with the surface in which it is installed) allow the connector to be used in place of standard AC outlets in many locations. Reach from an outlet to an appliance is therefore less of a concern, and the connector can be used in place of a standard electrical cord, thereby providing a safer, and less-obtrusive connection.
- the connectors may be used in multiple locations throughout the architecture of a boat or RV to provide quick release and installation of all fixtures (lights, radio, navigational tools, etc.) preferably without the use of tools.
- the fixtures will not tip over or come undone due to rough seas or roads, and all fixtures may be easily installed and uninstalled for versatility and ease of stowage.
- a plurality of connectors would be useful mounted in any type of grid pattern on one or more panels.
